Adding a note to @Yuraj's answer. Call the method in onWindowFocusChanged when hasFocus==true as follows to avoid indexOutOfBoundsException:

@Override
public void onWindowFocusChanged(boolean hasFocus) 
{
    super.onWindowFocusChanged(hasFocus);

    if(hasFocus)
    {
        Handler handler = new Handler();

        final Runnable r = new Runnable() 
        {
            public void run() 
            {
                if(mViewPager.getCurrentItem() == 0)
                {
                    Context context = Activity_main.this;
                    String filename="Init";
                    SharedPreferences stats;
                    stats = context.getSharedPreferences(filename, 0); 
                    int appOpen = stats.getInt("appOpen", 0);

                    if(appOpen <= 5)
                    {
                        animateViewPager(mViewPager, 10, 300);

                        appOpen += 1;
                        SharedPreferences.Editor editor = stats.edit();
                        editor.putInt("appOpen", appOpen);
                        editor.commit();
                    }
                }
            }
        };

        handler.postDelayed(r, WAIT_VIEWPAGER_NUDGE);

    }
}
